CTE Wind, global leader in civil engineering for wind turbine foundaiton design, celebrates remarkable growth and presence in 75 countries.

CTE Wind has experienced remarkable growth since its establishment in 2003. Over the past decade, the company’s expansion has been particularly noteworthy. In 2012, CTE Wind successfully implemented projects in 23 countries, including Canada, South Africa, and Greece. France accounted for the majority share of these projects. Presently, CTE Wind has extended its reach to an impressive 75 countries worldwide.

One of CTE Wind’s significant achievements in 2012 was the design and development of the Tarfaya wind farm in Morocco, which was then the largest wind farm in the country. Spanning across 10,000 hectares of land, the Tarfaya wind farm boasts a total capacity of 301 MW and encompasses 131 turbines. This remarkable project played a pivotal role in helping Morocco reduce its reliance on fossil fuels and achieve its renewable energy goals.

The wind energy landscape has undergone substantial transformations in recent years. Not only are wind farms becoming larger in scale, with installations exceeding 150 wind turbines becoming the norm in certain countries, but the wind turbines themselves are also becoming more powerful. In 2012, the average wind turbine had a power rating between 1 and 2 MW. However, today it is more common to see turbines with a capacity of 4 to 6+ MW. Furthermore, there is ongoing development in the industry, with Chinese original equipment manufacturers (OEMs) working on onshore wind turbines that match the power output of offshore generators. It is anticipated that in the near future, we may witness the emergence of turbines with an astounding output of 8 to 10 MW. This progress raises important questions regarding the design and construction of wind turbine foundations. As CTE Wind continues to innovate and expand its presence in the global wind energy market, it remains at the forefront of these advancements, consistently adapting its expertise to meet the evolving needs and challenges of the industry.

CTE Wind commissioned the Spanish University of Burgos to carry out a series of tests with the Soft-Spot™^®. The structural tests are intended to prove once again if and how the resource-saving wind turbine foundation solution for “onshore” wind turbines works.

Burgos (ESP)/La Richardais (FRA) – The University of Burgos was entrusted with testing the patented Soft-Spot™^® foundation solution from CTE Wind Civil Engineering for its functioning and safety at the end of 2021. The results of the test campaign, which ended at the end of May, confirmed what had already been demonstrated from many certification bodies worldwide and in various finite element models (FEM): The Soft-Spot™^® works and is safe.

Gapping occurs later

The Soft-Spot™^® changes the stress distribution on the ground compared to a standard slab foundation. Due to central EPS soft layer, higher soil stresses are applied under the remaining ring.

As a result, a wind turbine with a Soft-Spot™^® foundation will gap much later than a foundation without a soft layer, with the same foundation diameter. This increases the stability.

Over 1000 wind turbines…

…use the Soft-Spot™^® worldwide. The first project with the patented CTE Wind solution has been in place in 2019 in Thailand in a wind farm with 60 turbines. Each turbine has a hub height of 157 meters. Originally, a shallow foundation with 1,192 cubic meters of concrete and a diameter of 27.4 meters was planned.

But the excavation was not allowed to exceed more than 25 meters diagonally. Thanks to the soft layer under the foundation, the diameter could be reduced to 24.5 meters; minus 210 cubic meters of concrete (-18 percent) and 11 tons of reinforcing steel (-9 percent). The certifying body of DNV in Hamburg ensured that everything proceeded correctly and according to international standards during the design phase.

About CTE Wind Civil Engineering and the Soft-Spot™^®

The Soft-Spot™^® was developed by the French company CTE Wind Civil Engineering SAS. CTE Wind is an international engineering company specializing in the design and calculation of onshore foundations for wind turbines. The solution optimizes the existing and well-functioning system of shallow foundations by integrating known knowledge from structural engineering. Thus, a soft layer (EPS) is simply placed under the center of the foundation so that the forces of the wind turbine are transferred into the ground in a ring shape instead of onto the entire surface.

CTE Wind participates at the French national conference Colloque Nationale in Paris with an own stand.

The 12th National Wind Energy Conference, the major event of the wind energy industry in France, will take place on October 12 and 13, 2022 at the Parc Floral de Paris: wind energy professionals, experts, scientists, elected officials, associations and youth representatives will be gathered to continue the movement initiated 28 years ago by our industry: building the energy transition of our country.

For this 12th edition, the event continues, like our industry, to grow and diversify: more booths, more public, a greater diversity of actors for a greater cohesion between all those who participate every day to make, concretely the energy transition.

The road is still long, but the path is clear and the cause is righteous.

Bilbao (Esp) / La Richardais (FRA) – CTE Wind Ibérica has won again a contract in Spain to calculate and design foundations with its Soft-spot^® solution. This is an important milestone for CTE Wind International as now three wind farms on the Iberian Peninsula will take advantage of its cost saving design. In addition to these projects, CTE Wind’s clients are also adopting this solution in many other wind farms worldwide. Argentina, Brazil, Chile, France, Lithuania, Indonesia, Mexico, the Netherlands, Russia, Serbia, Sweden and Thailand to name a few. Over 50 wind farms around the globe, 750 wind turbines are using this resource saving solution which was introduced a while ago by CTE Wind.

« CTE Wind is proud of the confidence shown by its clients, and especially of the interest on applying the Soft-spot^® solution», Chief executive Alexander MARTIN said and added « Our design provides interesting advantages and cost saving in material consumption and civil works while being easy to be built. »

Simply the most economical foundation

The Soft-spot^® was developed by CTE Wind’s engineering team and is implemented in various countries around the world. As a result of his astonishing design this solution allows savings in concrete volume up to 15%, reduction of foundation diameter and total weight reduction of reinforcement bars of 7 to 9%. The earthwork to be handled is reduced too. In some cases, what is also important is the available space : with Soft-spot^® you need less surface for the foundation. The construction is very easy and the material for the soft layer can be easily purchased for a low price all over the world.

Get ready for the next hdt (Haus der Technik) convention in Essen about civil and geo technical topics in wind power projects. CTE Wind’s CEO Alexander MARTIN will join the event as speaker.

Modern wind turbines with their large hub heights and rotor diameters place very high demands on the ground. Therefore, the proper and professional execution of the geotechnical site investigation and foundation consulting, including the required stability verifications not only for the wind turbine foundations, but also for the stability of the crawler or mobile crane used, is of very high importance. The site-specific optimization of the wind turbine foundations and the use of methods for improving the subsoil can often lead to potential savings in the foundations of the wind turbine.

Best Case Scenarios

The conference deals with the proper and professional execution of geotechnical site investigations and foundation consulting for the subsoil of wind turbines and their access roads. The scientific correlations will be explained and approved procedures for site investigation and ground improvement/foundations will be presented using case studies.

The event will take place in Essen, Germany the 7th and 8th of December 2022

Since 2019 CTE Wind provides geotechnical engineering services to their clients. Over the last six months, Ana Bielza, Senior Engineer at CTE Wind Iberica has taken part in over 45 projects. We have asked her what she actually does and why her role is crucial for the foundation design of wind turbine generators (WTG).

Can you briefly explain to us what a specialist in geotechnical engineering like you does?
Ana Bielza: Geotechnicians apply scientific methods and engineering principles to predict the response of the ground to the foundation requirements. They then deliver this information to the civil engineers so they can design foundations accordingly.

What is the difference between common geotechnical engineering for bridges or building compared to the WTG-geotechnics?
Ana Bielza: There are not many differences. The ground has to be investigated with similar methods (drillings, geophysics, lab tests, etc.) and the same kind of parameters are needed. But the ground capacity is usually not what determines the foundation size, because most of the time the soil strength transmitted by a turbine foundation is not high. Besides, settlements in general are not important in this type of structures. But rotational stiffness can rather be the main ground parameter to manage and sometimes it can even set the foundation size.

CTE Wind offers his services worldwide

You worked on over 45 projects in six months, which is quite a lot. In which countries did you take a look at the ground?
Ana Bielza: Yes, there were many. It looks like our services are very appreciated by the customers (She smiles delighted). I worked for projects in Argentina, Australia, Belgium, Brazil, Chile, India, Indonesia, Israel, Lithuania, Mexico, Netherlands, Peru, Russia, Spain, Tanzania, Tonga, Turkey, and Ukraine. Of course, every country has its peculiarities. And I not only mean the different ground types you can find but also how the different investigations that are conducted and how the results are delivered.

Looking back on these last months, what were the challenges? Can you maybe share one or two projects with us?
Ana Bielza: Challenging projects are usually the ones located on recent soils in seismic areas and near to the shore (high water table). For example, we have done several basic designs for a huge project in India with 1000 wind turbines, located on a saline desertic zone most of the year. But during the monsoon season the landscape becomes a swamp, with water at ground level. It is a region with an extreme seismic risks, on a recent granular soil (potentially liquefiable) and very aggressive to the concrete. We had to analyze the ground with just four boreholes in an area for 1000 turbines!

Sounds like fun. As far as we know, there are no known cases of significant damage from liquefaction in wind farms. So, how did you solve this problem?
Ana Bielza: Well, with only four drillings for such a huge area, it was mandatory to be conservative, therefore, and according to the client, we worked with two possible scenarios. We hope they were representative for the situation in most of the future turbine positions. The civil engineer then follows our specifications and designs the foundations accordingly with piles.

Trust is an important key factor

Could you tell us about another project?
Ana Bielza: Another challenging project has been the one in a country in South America, a wind farm with over 40 turbines. This was a constructive design where we had also drafted the geotechnical study from a factual report given by the customer, with 45 boreholes, 80 trial pits and 46 geophysical tests as well as an important amount of laboratory tests. The ground was good, a consolidated gravely soil -a conglomerate-, but seemed to be prone to suffer some dissolution because it had salt in its matrix.

What does it mean exactly?
Ana Bielza: The matrix describes the different layers a soil can have. The salt in the matrix can be dissolved by heavy rain or ground water. But even if the ground suffers an hypothetical dissolution, the remaining gravely soil would show enough strength and rigidity to carry the WTG. Besides, there was no water at all in the area, it was in a desert area.

Good conditions. What was the problem then?
Ana Bielza: Yes, but the client was pressuring us to set down categorically that there was no risk of dissolution, and there was no possibility at all for buoyancy. The geotechnics of the project showed good conditions for our SOFT-SPOT® foundation, but the wind farm owner seemed to have unfounded fears and wanted us to affirm that there was zero risk in this area. But zero risk does not exist. It was tricky to explain why there are no risk but we had to write about an hypothetical dissolution. Luckily, we finally came to an understanding. (ctewind)
